* [9fans] MIPS LE fp register ordering in MOVD @ 2013-12-24 17:20 cherry 2013-12-26 23:46 ` cherry 0 siblings, 1 reply; 13+ messages in thread From: cherry @ 2013-12-24 17:20 UTC (permalink / raw) To: Fans of the OS Plan 9 from Bell Labs [-- Attachment #1: Type: text/plain, Size: 4062 bytes --] Hello Fans, It seems 0l/vl in little endian mode outputs wrong ordering of fp registers in MOVD. For a double, which is stored in an even-odd pair of fp registers, the least significant bits should be held in the even numbered register, regardless of the endianess. When moving from/to memory, in LE mode the first 4 bytes should go to even numbered registers, which is different from BE mode.
